In the dynamic use cases, the PCIe specs is kind of shabby on the addressing space: it is theorically fixed by FPB.

I guess this is sorry for those niche hardware use cases.

Isn't FPB into PCIe 4.0? (I am not a SIG member, cannot read the specs).

I meant, I know about PCIe addressing (from the web, linux code, and a book I read years ago), but I cannot read the modern specific FPB specs.
